' To all whom it may concern/.

Be it known that I, SAMUEL MATTsoN, of NewYork, (Brooklyn,') in the county of Kings and State of New York, have invented cer- 5 tain new and useful Improvements in Derrick Apparatus; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to IO make and use the same.

The invention will be hereinafter fully set forth, and particularly pointed out in the claims.

In the accompanying drawings I have shown one form of mechanism in which my invention may be embodied, but to which form my invention is not limited.

Figure 1 is a view showing the general outline of a hoisting apparatus and derrick'con- 2o taining my invention. Fig. 2 is an enlarged View of a part of the hoisting apparatus. Fig. 3 is an enlarged vertical sectional View taken through one of the friction-drums. Fig. 4 is an elevation of one of the latter. Fig. 5 shows one of the clutches.

Referring to the drawings, A designates a hoisting apparatus; a, a mast; a, a boom extending from said mast, and on a bull-wheel k'eyed on mast a.

The hoisting apparatus A is provided with two friction-drums b b, which may be operated in any suitable manner in accordance with well-known forms ofconstruction, such as that shown in the Beekinan patent, No.

5 541,308, dated June 18, 1895.

40 The shafts B of the friction-drums b b have their bearings in two frame members. On the extended end of the shaft B of each drum, overhanging outside oneof the frame members, isplaced a supplemental friction-drum winch-heads are connected the ends of a rope W, which is" passed aroundthe bull-wheel a and by which the mast a is capable of being rotated. Each winch-head consists of a central part or section D and two end parts or sleeve of section (1'.

a is the rope by which the fall-block a for carrying the load is raised and lowered by one of said To these sections (1 d. The former, D, has an annular concavity to accommodate the rope Wand is normally loose, while the parts or sections (1 d are interlocked and held to their shaft, so that they constantly revolve therewith, and one of them is capable of being so 'moved on said shaft as to bind all three parts or sections in frictional contact. The part or section d" consists of a hub or sleeve (1 and an outer circular flange d This section is held firmly on shaft B by an extension d thereof, a bolt d f, and a washer d". The inner end of this sleeve d has two opposite cut-aways, forming two prongs or extensions (1 On the inner face of the flange (i near the periphery thereof, is formed an angular V-shaped groove 6,

designed to conform with and accommodate an annular V-shaped rib e, formed on the outer side of the central part of section D.

The part of section d consists of a central'7o hub or sleeve 6 and a circular flange e the latter being formed near its peripherywith an annular V-shaped rib e, which is designed to project into and snugly fit a corresponding groove e in the adjoining face or end of section D. The end of the hub or sleeve e is also provided with opposite cut-aways e, which accommodate the extensions d of the This latter section being fast to shaft- B and its sleeve being in engagement with the sleeve of the part (1, both are caused torevolve in unison with said shaft. The cut-away portions in the sleeves d and e are of such depth as to permit the section at to have a limited sliding movement on shaft B without being disengaged from the sleeve of the section (1. On the shaft B of each of the drums of the hoisting apparatus is placed a clutch E, the same consisting of two collars f f, the'former being stationary 0 and the latter loose, bothv having concentric openings to accommodate shaft B. The inner opposed faces of these collars have camlike inclinations, whereby by moving the collar f so that the opposed faces of the two collars will force it outward against the adjoining face ofsection d of the winch-head said section will be moved so as to bind in frictional contact the three sections of the head. It will be understood that the inclinazoo tions of the collars of one clutch are the rel for success and safety. By employing the verse of those of the collars of the other'clutch. From each of the collars f projects an arm These arms of the two clutches are connected together by a bar f and with the center of the latter engages an operating-lever F, which is operated from a hand-lever F, located at'the opposite end of the'drums'b and b and connected with the lever F by a rockshaft F extending across the machine substantially parallel with the axes of the drumshafts. The clutches are so arranged that when one of them forces the parts of the sections of the adjoining winch-head into frictional engagement with one another the other clutch will release the sections of the other winch-head, thereby allowing the rope or central section D to rotate independently of the shaft B, as well as of the other parts or sections of the head. a By adjusting the bolt d the power of the friction for a given position of the clutch or cam memberf may beregulated and kept substantially constant notwithstanding the ,wear of the friction-surfaces. The hand-lever F is located at the same side of the machine with the handles ,(one of which, F is shown) by which the attendant controls the frictions operating the drums b and b, respectively. From what has been said it will be seen that by means of my invention the mast of a derrick can be readily and easily turned and the boom carried thereby may be held at any desired point.

winch-headsas being so constructed and arg ranged that as one is having the rope wound While I have specified the thereon the rope is being unwound from the other, yet by so moving the operating-lever:

F'- and holding it at an intermediate point bothlwinch-heads may be loosened as not to cause the rope-sections to rotate with their respective shafts.

' I use the term winch-head inthis application as a convenient term to designate the windingdrum 0, because I employ them for the operation of thebull-wheel rope W in lieu of ordinary winch-heads. use of the term Winch-head do not limit myself to the form of either of said windingdrums O or to its location upon its shaft rela tively tothe frame or other parts of the ma chine.

In the operation of friction-drums of a derrick-engine for hoisting and lowering the load and boom, respectively, it is Well known that v the operator stands within reach of the han- -dles F at the opposite end of the drums from the winch-heads and that it is necessary for safe and successful operation of said drums that he should remain at that position. Hence the utilization of the winch-heads heretofore for the operation of the bull-wheel rope has required it to be done by another man ormen, and it was impossible to control the bullwheel rope relatively to the boom-hoisting and load-hoisting ropes with that degree of promptnessand precision which are desirable I therefore by the supplemental friction -drums C and G as winch-heads and coupling their friction and controlling mechanisms together and combining with them a connection extending to a hand-lever at the opposite end of the drums b and b the operatorof the drums 1) 125 may without substantially leaving his position operate the winch-heads of supplemental friction-drums O O. Therefore my invention puts it in the power of a single operator to control with promptne ss and precision and safety not merely the ropes for raising and lowering the load and boom, but also the rope for swinging the boom,which, so far as I know, is a result never before accomplished by a derrick-engine.
